One of the most common use of JSON is to fetch JSON data from a web server (as a file or as an HttpRequest), convert the JSON data to a JavaScript object, and then it uses the data in a web page.

The eval() function can compile and execute any JavaScript. This represents a potential security problem.

It is safer to use a JSON parser to convert a JSON text to a JavaScript object. A JSON parser will recognize only JSON text and will not compile scripts.

* JSON full form is JavaScript Object Notation.
* JSON is a lightweight text-based open standard designed for human-readable data interchange.
* It is derived from the JavaScript programming language for representing simple data structures and associative arrays, called objects.
* And JSON is language-independent, with parsers available for virtually every programming language.
* Uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python,php
* The JSON format is often used for serializing and transmitting structured data over a network connection.
* When third party data interchane(REST Services) then JSON may used there LIKE SHOP.
* It is primarily used to transmit data between a server and web application, serving as an alternative to XML.

P = Rs. 900, R = 3 ½ % = 7/2 %, T = 2 years. 

Therefore, 

S.I. = PTR/100

S.I. = Rs. (900 x 7/2 x 2/100) = Rs. 63

Now, P = Rs. 200, S.I. = Rs. 63, R = 5 %

Time = ((100 x 63) / (200 x 5) ) years = 6.3 years.
